How resico in Mexico is calculated
RESICO carries the lowest rates in this entire catalog, and the reason is structural rather than generous: it taxes gross income actually collected, with no deductions of any kind. A 2% rate on revenue is not comparable to a 2% rate on profit, and the regime is only attractive where costs are genuinely small relative to what you invoice.
The rate is set by monthly income, not annual, and the monthly payment is definitive rather than an advance — there is no annual reconciliation that could claw more back. That makes an uneven year behave differently from a level one with the same total: each month is priced on its own.
Worked example
| Annual income collected (MXN) | 600000 |
|---|---|
| Monthly Income ✓ | 50000 |
| ISR rate (%) ✓ | 1.1 |
| ISR / year ✓ | 6600 |
| Net income / year ✓ | 593400 |
Every row is computed by the engine from the inputs above. Rows marked ✓ are additionally pinned by a published self-test vector.
Frequently asked questions
What is the ISR rate under RESICO?
Between 1% and 2.5%, set by monthly income: 1% up to 25,000 MXN a month, 1.1% to 50,000, 1.5% to 83,333, 2% to 208,333 and 2.5% above that.
Can I deduct expenses under RESICO?
No. The rate applies to income actually collected, with nothing deducted. That is the trade for rates this low, and it is why the regime suits service work with minimal costs.
What is the RESICO income limit?
3,500,000 MXN of total annual income. Exceeding it removes you from the regime and returns you to the general regime for personas físicas con actividad empresarial.
